Croze-Cutting Tools, of which the hollow-- is a full, clear, and exact descriptiomf had to the accompanying in re erence being drawings, formlng apart hereof.

My nvention has relation-to improvements in rotary croze cutting tools or cutters; and it consists in thenovel dQtaIlS' of construction more fully'set 'forth inothe speci fication and pointed out in the claim.

I e In the drawings, Figure. 1 represents a perspective of a conventional type of crozinvention a pliedthereto; Fig.2 is aside --and Fig.8 is a longitudinal section ofthe "barrel wa1lshowing the croze applied cask C is held'a y S ofthe'vibrating' carriang andchamfering machine showing my elevationp the c'rozing tool detached; Fig.

thereto;

gI-he present invention is designed for use:

in connection with comparatively thick stavesin which a shoulder or ledge is cut in oovefor the sup-.

lieu of the prevailing, I port of the head theob ect being to provide a tool with sevoralkin ependent cutters or axis and res ctiv'ely chamfering, dressing, (or dove-tailing) sections rotating in unison about a common bevelingan shoulderin the assembled stoves without grabbing. A further object is to'construct a tool which-"isjfstrong, readil adjusted, easily laring further and other advantages better apparent from'a detailed description of the nvention whichis as follows is; V

the base'of a conventional machine rovided Referring to the drawings, B represents with a stationary chuck-ring Ran anfadjustable chuck-r1 '11 between which the h s I slowly rotated" throu h the instrumentality of the cog-wheel; V identified with the adtstable ring'RC, .The cutters'M operate wit "n the cask (one cutter at each end) being mounted on the shafts p V and revolved by belts D passing over t e pulleys P on the carriages.

ing'for the machine is merely referred 'fact *referenceis made only to those parts 'with 'whi'ch'the cutters are directly assoc1- ated,namely,- the rings R; R, by which the cask (or barrel )is rotated. The invention pro er, however, is confined to the cutter, and

III etail is as follows :-To the free end of the shaft S- or the end inserted into the cask 'ishe ed a circular member or disk 1 provide with radial recesses or grooves r for the reception of the shoulder .cuttin blades or cutters 2, the cutters bein a ustable radially in their recesses and w en once ad- 'justed are rigidly clamped by the nuts 3 passed over thescrew-studs' 4 carried by the cutters and rojectin' from the outer face ofthe disk t rough e ongated slots a in the outer walls of the recesses 1*, said slots allowjustment of thecutters as chvious. Passed over the shaft S and engaging the disk 1 is a member 5 the form of the frustum of a p amid, the base of the frustum being on t e-side toward the disk.

About the faces of the frustum are iSPo'sed blades 6, the latter bein "rovided with longitudinal slots 7 '(Fig. 2% or the passage therethroug'h of the screw-studs 8 -rejecting from the faces of the member 5, e studs carrying clamping nuts 9 by which the blades are securely fastened to the member 5 when once properly adjusted. The blades 6 serve to cut the bevel'b on the inside of the cask'G, the blades 2 forming the shoulder a by which the head of the cask is supported (F1 8).

In practice the member 5 is so a justed or turned on the shaft S, as to brin the cutting edges of the blades 6 to one si e of the cutting edges of the cutters 2 (Fi 4) this arrangement preventing the vbungling and crowdin of the cuttings and shaviu removed by t e tool. Passed over the she, t S and engaging the narrow end of the mmher 5 is a pyramid-frustum or member 10 terminating at its narrow end in an elongated head 11 integral therewith; the sides,

of the head 11 being bounded by the-sidesof the head 11 inclined grooves 13 for the reception of the bases of the chamferin blades 14. These 'blades are additiona ly secured to the wings 12 by means of nuts 15 passed over thescrew studs 16 projecting "from the faces or the wings A through slots 17 in the blades, said slots alfor the proper adjustment of the The latter cut the chamfer 0 from of the stave (Fi 8). Disposed F the frustum 10 slots 19 (Fig.

lowing blades. the edge about the inclined walls 0 are blades 18 provided with 2) for the passage therethrough of the" screw-studs 20 projecting from the frustum wall, the nuts 21 clamping the blades in position when once adjusted. The blades 18 dress the surface 03 on the stave (Fig. 8). The shaft S is provided with a screwthreaded portion beyond the head 11 (Fig. 6) over which is passed a clamping nut 22 by which the several members or sections 1, 5, 10, carrying the cutters or blades are rigidly clamped together so as to rotate as a unit with the shaft S, the free or inner end of the latter terminating in a head It against which the member I niay bear as an abutment when the nut 22 is driven home.

The operation is clearly understood from the foregoing. Once the several cutter sections or members with their blades are adjusted and secured on the shaft, a rapid rotation is imparted to the shafts S pro ecting from the carria es V into the barrel or cask, a slow rotation icing at the same time given the latter but in single rotation of the cask will suffice to cause the tool to impart the necessary chamfering, dressing and dovetailing (beveling and shoulderin to the staves (Fig. 8), the formations a, f, 0, cl, being 'cut in the cask at each end. Obviousl y, the tool operatin at one end of the cask must be right-hande and that at the opposite end left-handed,

that is to say, the blades must be set so as to out while turning at one end, relative to the observer, in the direction of the hands of the clock, while at the other end they Copies of this patent may be obtained for the opposite direction. A'

would be turning in a direction the hands of a clock.

The present tool may be readil kept in repair since the cutters and b ades are readily removed from the head and sha ened. Obviously the cutting edges of t e blades 6 are disposed in a circle interior to the cutting edges of the radial blades or cutters 2.

Having described my invention, what I claim is A croze-cutting tool terminal disk keyed thereto an with radial grooves, said grooves and projecting beyond the periphery of the pyramid-frustum body portion mount on the shaft and engaging the disk aforesaid, blades on the faces of the frustum having cutting edges disposed in a circle interior to the free cutting edges of the radial blades of the disk, a second pyramid frustum engaging the first frustum, and forming substantially an extension of the first frustum,

opposite to comprisin a shaft, a provided cutters deposited in.

disk, a member havin a I blades on the faces of the second frustum, an outer terminal member on the shaft coupled to the second frustum and comprising a central head, lateral outwardly divergin Wings forniin inclined slots or grooves wit the sides 'bf t in said grooves and supported by, and secured to the wings, the succession of blades starting from the last set successively chamfering, dressing, bowling and shouldering the assembled staves, as set forth.

In testimony whereof I afiiz; my signature, in presence of two witnesses.
